fwlogwatch produces ipchains, netfilter/iptables, ipfilter, Cisco IOS and Cisco PIX log summary reports in text and HTML form and has a lot of options to find and display relevant patterns in connection attempts. With the data found it can also generate customizable incident reports from a template and send them to abuse contacts at offending sites or CERT coordination centers.
